Luke 1:5
In the time of Herod king of Judea there was a priest named Zechariah, who belonged to the priestly division of Abijah; his wife Elizabeth was also a descendant of Aaron — the transition from the prologue's literary Greek to the Septuagintal Greek of the infancy narrative is abrupt and deliberate: Luke is signaling that the story he is entering belongs to the world of the Old Testament. In the time of Herod king of Judea grounds the narrative historically; the precise priestly lineage of Zechariah and Elizabeth communicates their standing within the covenant community.
